Ultra
AFS's ultra high aspect downwind wing at aspect ratio 14, the design behind the Fuselink version, with a bump technology on the leading edge that allows an ultra-fast section without penalising the low end. AFS's downwind experts suggest trying it on the titanium fuselage. Sizes 600, 750 and 900.

Entering Flow State: Winging the AFS Ultra 750
Tested: Ultra 750 (own purchase)
Pros
- Stiffest high-aspect wing the reviewer has handled
- Very long glide (about 3 miles flagged out in one test)
- Rips small swell and stays nimble in big swell
- Fast, steep upwind and high average speeds on long sessions
Cons
- Nuanced: needs the right mast, tail and board to feel at home
- Not a mellow cruiser; wants to be ridden aggressively
- Less of a carve than the Silk and not the pick for wing tricks
Verdict: A high-performance surf glider for riders who push hard in swell.
